It is then immaterial which method of comparison is adopted — gallons of 

 milk for those who think in that way, or pounds of butter for those who 

 prefer to make their comparisons on that basis. 



Tlie tested cows are also divided into three groups, cows with a milk record 

 equivalent to not less than 2,500 gallons at 1 per cent, fat and heifers with 

 a milk record equivalent to not less than 2,000 gallons at 1 per cent, fat 

 forming Group I ; cows yielding less than 1,600 gallons and heifers less than 

 1,300 gallons milk forming Group III ; and all between those two quantities 

 forming Group 1 1. The following table shows the corresponding values of 

 these yields in milk, taking the different standards of quality : — 



Records of the Scottish Association later than 1915 are not available, but 

 those before us show that whereas in 1914, 39-|- per cent, of the cows tested 

 came into Group T,in 1915, 46 per cent, reached that standard. Considering 

 the disabilities under which dairy farming was carried on during that time, 

 through lack of all kinds of food for stock, this was a creditable performance, 

 and shows that the average yields of the herds were incieased by testing. 

 This improvement is also exemplified in the cases of several particular herds. 

 The following little table is well worth the attention of herd owners here : — 



In each case there has been a marked improvement in the standard 

 of the cows kept, an invariable concomitant of testing, it may be 

 said. In No. 1 herd, for instance, the percentage good enough to come into 

 Group I advanced from 39 in 1910 to 64 in 1911, and reached 8S
